Identification of environmental impacts caused by release of waste in the Itapecuru River

Abstract

In this study, we analyzed the environmental problem identifying the main impacts caused by garbage released on the Itapecuru River, which contributes to the impairment of water quality of the water body in question. The main activities and processes responsible for the environmental degradation of the river are related to the inadequate disposal of garbage and the launch of waste through untreated sewage. Bibliographic research, field activities, and photographic records were carried out. The results showed that in the area evaluated the domestic sewage from the residents' residences, near the banks of the river, is thrown directly into the water body without previous treatment, which can cause several problems, such as: pollution, imbalance of the aquatic ecosystem, in addition to unpleasant odor, it was observed that the interventions of public sectors in the situation found are minimal, the population is bothered by both visual and water pollution, but do not have the means for a disposal of garbage and choose to discard them in the most accessible. Way besides not knowing environmental protection laws, residents close to the banks of rivers have little knowledge about basic sanitation and one of the main reasons for degradation is associated with the occupation and use of urban soil by man. Thus, it is concluded that in the vicinity of the Itapecuru River there are environmental impacts caused by the action of man and are several factors that contribute to the degradation of the aquatic environment, including the launch of garbage.
